bad328a72e pieeprom-2025-02-11: 2711: Walk partitions to delete recovery.bin (latest)
* recovery: Walk partitions to delete recovery.bin
  Previously, recovery.bin would fail to delete itself
  if the bootrom loaded recovery.bin where there are multiple FAT
  partitions and the first partition does not contain recovery.bin
  Update the rename code to walk the partition table to find
  the recovery.bin file to delete.
* Enable overriding of high partition numbers
  Previously, the PARTITION=N bootloader config setting would only
  be used at power on reset or if the partition number passed to
  reboot was zero.
  Change the behaviour so that the bootloader config PARTITION
  property can override the reboot partition number if the reboot
  parameter is > 31.
* Walk the partition table if the requested partition is not bootable
  Previously, if the specified boot partition was not bootable the
  bootloader would stop and advance to the next BOOT_ORDER. If the
  new PARTITION_WALK option is set to 1 the bootloader will now
  check each partition in turn starting from the specified partition
  before advancing the BOOT_ORDER.
  This feature is intended for use with A/B systems to handle the case
  where autoboot.txt is missing / corrupted. This change enables
  the system to failover to the next available bootable partition.
  The autoboot.txt file is not scanned during the partition-walk
  phase i.e. there is no recursive processing of autoboot.txt files.
  This option is only supported on physical block devices
  (SD, NVMe, USB) and not RAMDISK. USB assumes a single high speed
  device, partition walks on multiple USB devices is not recommended
  and may cause timeouts.
* Improve keyboard handling in boot menu
  Try and make it more likely that we have enough time to perform key
  detection.
  Ignore mice, which were being enumerated and slowing things down.

34eab17ce6 pieeprom-2025-02-11: 2712: CM5 no-wifi stability improvements (latest)
* recovery: Walk partitions to delete recovery.bin
  Previously, recovery.bin would fail to delete itself
  if the bootrom loaded recovery.bin where there are multiple FAT
  partitions and the first partition does not contain recovery.bin
  Update the rename code to walk the partition table to find
  the recovery.bin file to delete.
* pi5: Add config filter for simple boot variable expressions (experimental)
  Add support for a new bootloader/config.txt conditional filter
  which tests the partition, boot_count and boot_arg1 variables.
  Syntax (no spaces):
  ARG boot_arg1, boot_count or partition (EEPROM config stage only)
  [ARG=VALUE]      selected if (ARG == VALUE)
  [ARG&MASK]       selected if ((ARG & VALUE) != 0))
  [ARG&MASK=VALUE] selected if ((ARG & MASK) == VALUE)
  [ARG<VALUE]      selected if (ARG < VALUE)
  [ARG>VALUE]      selected if (ARG > VALUE)
  where VALUE and MASK are unsigned integer constants and ARG
  corresponds to the value in the reset register before the
  config file is parsed.
* pi5: Add a boot-count bootloader variable (experimental)
  Store the boot-count in a reset register and increment just
  before the boot-order state-machine. The boot-count variable
  is visible via device-tree /proc/device-tree/chosen/bootloader/count
  and can be read/set via vcmailbox
  GET: sudo vcmailbox 0x0003008d 4 4 0
  SET to N: sudo vcmailbox 0x0003808d 4 4 N
* pi5: Add user-defined reboot argument (boot_arg1) (experimental)
  Add support for a user-defined boot parameter stored in a reset-safe
  scratch register on BCM2712.  This is visible via device-tree at
  /proc/device-tree/chosen/bootloader/arg1 and via vcmailboxes
  GET arg1: sudo vcmailbox 0x0003008c 8 8 1 0
  SET arg1 to 42: sudo vcmailbox 0x0003808c 8 8 1 42
  or via config.txt
  set_reboot_arg1=42
  The variable is NOT cleared automatically and will persist until
  a power-on-reset.
* Enable overriding of high partition numbers
  Previously, the PARTITION=N bootloader config setting would only
  be used at power on reset or if the partition number passed to
  reboot was zero.
  Change the behaviour so that the bootloader config PARTITION
  property can override the reboot partition number if the reboot
  parameter is > 31.
* Disable WiFi PMIC output on CM5 modules without WiFi
  Disable the 3.7V WiFi power supply on CM5 modules which do not have a
  WiFi module fitted. This fixes some stability issues where a CM5
  would shutdown due to a spurious over-voltage condition on the
  non-connected WiFi power supply.
* Add memory barrier to the mbox handler
  Firmware issue 1944 reports receiving kernel warnings about firmware
  requests where the status return code is 0. This should not be
  possible, as handle_mbox_property always sets the top bit of the return
  code, with the bottom bit indicating success or failure. If the firmware
  had died, the firmware driver would report a timeout due to the lack of
  a mailbox interrupt, and that isn't happening.
  See: https://github.com/raspberrypi/firmware/issues/1944
* support dts files with size-cells of 2
  DTS files with a top-level #size-cells of 2 make a lot of sense for
  systems with a lot of RAM, but the firmware is currently inconsistent
  in its support for that. Fix up the other cases to honor #size-cells
  and #address-cells.
* Disable SDIO2 for CM5s without WiFi
  It has been observed that CM5s without WiFi hang on reboot. To prevent
  that, disable the sdio2 node on those devices.
  See: https://github.com/raspberrypi/linux/issues/6647
* arm_dt: Use dtoverlay_enable_node
  Convert the open-coded DT node status changes to use the new dtoverlay
  method dtoverlay_enable_node.
* dtoverlay: Add dtoverlay_enable_node
  Add a helper function for setting the status of a node.
